To all whomc't may concern.-

'Be it known that we, MABcUs BEEMAN and JOHN F. KITCHEN, residents ofMeadville, in the county of Crawford and State of Pennsylvania,. haveinvented a new and useful; Improvement in Devices for StraighteningMetal Strips, of which the following is a specification.

This invention relates to devices for straightening metal strips, andmore particularly to devices for straightening strips formed by bendinwire into a series of loops to form a fa ric to afterward cut intosuitable lengths to serve as garment stays.

The fabrication of garment stays from a high quality of steel wire bybending the same into a series of loops produces a strip which curvesand kinks to varying degrees, due to the action of the bending devices,

variations in the temperand twistof the wire and other causes. The stripor fabric must be straightened before the product can be used forgarment stays.

The resent invention has for its object to provide a device forstraightening such strips, by means of which the strip is entirelyrelieved of its curls, bends or curves, and caused to be strai ht andflat, and which device is so arrange as to be readily adjust-ed orvaried to exert varying degrees of efiect on the strip according to thevarying conditions of the latter.

The invention vcomprises the construction and arrangement of partshereinafter described and claimed. t I

In the accompanying drawings Figure 1 is a side elevation of the device;Fig. 2 is avertical transverse section on the line 2- 2,' Fig. 1; Fig. 3is a similar view on the hue 3-3, Fig; 1; Fig. 4 is in part a plan viewand in parta horizontal section on the line 4-4, Fig. 1; and Fig. 5 is adiagrammatic view of a modified form.

The frame of the device is a casting comprising the base 1, and anupright or web relatively low portion '2 and a.

having a relatively high portion 3. The base 1 near one end is providedwith an opening in which are set guide or wear blocks 4:, 5, and groovedto form a. passage for the strip ltherebetween and secured by screw 5work-" a threaded 1101s in the base 1.

e strip 7 to be straightened passes updevice between the guide or wearblocks 4 and 5-but it is not intended to exert any -;fr1ct1on orpressure thereon at this point,

The'strip passes thence over an idle guide roll 9, wh ch rotates on asuitable, pin mounted 1n the web. The roll 9 is grooved to receive thestrip and cooperating-therewith isa tension spring ll -which presses onthe strip to exert the necessary tension thereon. This spring isseuredto a headed stud or bolt 12 rotatable in a hole in web 2, and isfrictionally held thereon by a nut- 13 and spring 14 on its one enddrawing its head 15 against the low portion 2 of the web. By means ofthe nut the trio 'on can be varied as desired to hold the spring 11 withany desired tensionon the strip tobe straightened.

The-stud or bolt 12 .can be turned or rotated in either direction, bymeans of handle 16, to any desired position, the friction of nut 13 andspring 14 being suificientto hold the stud or bolt in adjusted.position. For convenience in inserting the strip to be straightened thetension spring 11 can be swung entirely clear of roll 9, if so desired.

From the idler roll 9 the strip 7 passes over a swinging roll 18, thenceover a small roll or stud 19, and thence over a horizontal grooved guide20 and out at the rear of the machine. The guideblock 20 is secured tothe web 3 of the frame by means of screw 21 or other suitable means. Themember 19 is a small roll running idly on a small arbor or shaft 22,provided with a head 23 to keep the roll in place and clamped in a splitblock or bushing 24, securedin an opening in web 3 and clamped thereonby suitable means.

The swinging roll 18 is journaled on a headed stud 27 securedto acircular member '28 set slightly eccentric to the axis of the sition'forinspection of the straightening rolls, and for convenience in insertingthe strip to be straightened.

wardly into the forward or front part of thev (Q PatentedJam21, 1913.

The ircular member 28'carrying the roll the quality thereof and theamount of stress to be applied thereto to straighten the same.

In Fig. 1 the dotted line position a indi cates the extreme lowerposition of the .roll 1-8 in which the strip can take a straight coursefronridler 9, under' roll 19 and over I guide'20. At f is'iudicated theextreme upper position of roll 18 in which position thestrip-7 is givenmaximum deflection. It can be held at any point between these twoextremes, and is adjusted by. the operator by means of hand wheel 35.The operator watches the effect of the rolls on the strip.'7 and adjuststhe position of roll 18 back and forth depending upon whether the deviceis failing to take all of the curvature out of the strip or isoverdoing'the same. The roll is stopped in its lowermost position byabutting the guide 20, and in its extreme uppermost position byapproaching the roll 19 so closely as to be stopped by the strip 7between said rolls. i The roll 18 is held'in adjuste'd positionfrictionally by means of helical spring 37 interposed between hand wheel35 and a plate 38 surrounding hub 34 and bearing against the outer faceof the'swinging plate 29. The spring draws the, rotating member '28outwardly and'brings a-flange 39 on its periphery against a shoulder onplate 29 with suflicient pressure to frictionally hold the member 28with roller"1 8' in any position to which it may be moved ,by means ofhand wheel 35. p a

The strip 7-may be drawn through the device by hand or by any suitabletraction device, such as a reel, spool or the like, but

device byimeans of'a pair of driven "rolls placed at the rear of thedevice and pinching the strip therebetween. As such traction devices arewell known in the art, the action thereof will be readily understood.

In Fig. 5 we have illustrated somewhat diagrammatically a modified formof device in which the fixed guide 2O is replaced by a movable guide. Asshown the guide consists of an idle roller or wheel 42 mounted forrotation on a stud or pin 43 secured to the high portion of the web 3and located below and slightly in advance of the stud 19. Preferably theroll 42 is. grooved to receive the strip 7 in the same manner as theguide 20. Other forms of guide will readily suggest themselves.

The operation of the device will be readily understood from theforegoing descrip tion in connection withthe drawings. The

device is of simple construction and readily strips, the combination ofa deflectiontathestrip to instantly meet the ,varying conditions of thestrip to be straightened: the parts subject to wear are readilyaccessible and can be easily replaced in case of=excessive wear.

Ve desire to be understoodthat front and rear, appearingdn thespecification and claims, are used with reference to'the places ordirection of entrance and exit of v the strip from the device. In otherwords, the guides nearer, along the line of movement of the strip, toits place of'entrance may be considered as in front of those guideswhich, are nearer to the place of exit. of the strip, which is at therear of the device. i

\Vhat we claim is:

adjustable to give any desired amount of a 18 is provided with axialprojection or hub 34 to which is secured a hand wheel 35' by means ofwhich the plate 28 can be rotated to vary the position of the roll 18to. more or less deflect the strip 7, depending on 1.
